What is carry increment adder?

The two n-bit adders are redundant in that both contain the initial PG logic and final sum XOR. It reduces the size by factoring out the common logic and simplifying the multiplexer to a gray cell, as shown in Figure 11.25. This is sometimes called a carryincrement adder. It uses a short ripple chain of black cells to compute
the PG signals for bits within a group. The bits spanned by each group are annotated on
the diagram. When the carry-out from the previous group becomes available, the final gray cells in each column determine the carry-out, which is true if the group generates a carry or if the group propagates a carry and the previous group generated a carry. The
carry-increment adder has about twice as many cells in the PG network as a carry-ripple adder.

How to Calculate Carry-Increamentor Adder Delay?
